4 Claims. (01. 184-81) My invention relates to oiling devices, and more particularly to oiling devices wherein oil is discharged in measured quantities, into a plurality of tubes, each leading to a bearing requiring lubrication. One object of this invention is to provide an oiling device which automatically starts and stops with the starting and stopping of the machine being lubricated. Another object is to provide an oiling device which has a dependable, uniform, adjustable, and visible rate of flow. Another object is to provide an oiling internal mechanism.

Fig. 2 is a sectional elevation, the section being made on the line 2, 2, in Fig. 1.

In carrying out the purpose of this invention, the mode of operation includes broadcasting minute particles of oil, which are projected outwardly from a common source, in various directions along multitudinous paths, some of which lead to a plurality of receiving stations, where the oil is received, and then delivered to a plurality of tubes, each leading to a bearing requiring lubrication.

The oil reservoir ll] contains oil I2, which is to be delivered to the bearings requiring lubrication. The oil pump 14 comprises a rotatable tube 15, which surrounds a stationary shaft is, having a helical groove l9 extending throughout the length of the shaft l8. When the tube I6 is rotated in a clockwise direction, as viewed from above, oil is discharged upwardly through the tube It, and outwardly through the ports 20, upon the rotatable disc 22.

The electric motor 24 rotates the tube l6, and also the ,disc 22, which is rigidly secured to the tube 16. The cover 26 supports a plurality of targets 28, each of which is superimposed over an oil well 30, having a drip tube 32, arranged to Operation The electric motor 24 is connected in multiple with the electric motor that drives-the machine to be lubricated, so that when the machine is started in operation, the electric motor 24 is also started, thereby causing rotation of the tube l6 and the disc 22. Centrifugal force then causes the oil to be spread over the surface of the disc 22 in a thin film, which is broken up at the periphery of the disc ,22. to form minute droplets, which are projected away from the disc at considerable velocity, in multitudinous, tangential, horizontal directions, thereby forming a disclike stream pattern. Some of these droplets of oil impinge upon the targets 28 and collect thereon in sufiicient quantities to cause the accumu-.

lated oil to drip from the targets 28 by the action of gravity, thereby feeding the oil wells 30 and feed tubes 36.

Owing to the conical construction of the targets 28, a larger area of each target is exposed to the continuous bombardment of oil particles when the target is adjusted downwardly, and 'a smaller area is exposed when the target is adjusted upwardly. Thus each target may be adjusted to provide the proper supply of oil for lubricating the corresponding bearing. It is to be understood that the oil wells 30 are positioned at an elevation greater than that of the bearings being lubricated, so that oil may flow by gravity from each oil well 30 to its corresponding bearmg. a

While the drawings illustrate but one embodiment of this invention, many modifications of the specific construction shown may be readily suggested. For instance, oil may be fed tothe rotating disc by gravity, instead of by a pump; or, in the distribution of the oil, the quantity of oil delivered to each bearing may be determined by providing fixed targets, each partially screened from the projected oil particles by adjustable barriers; or the targets may be replaced by orifices of adjustable area. Also, the oil could be scattered by compressed air or other mechanism, instead of the revolving disc shown in the drawings. These modifications and others could be made without departing from the spirit of the invention, which is to be limited only by the following claims.

I claim:

1. In a device in the class described, an en- 'closed reservoir for containing oil, oil scattering means within said reservoir for throwing said oil through space in a pattern of minute droplets confined to a relatively thin horizontal stratum,

a plurality of targets disposed to intersect the said oil stratum and each of said targets having portions of greater and lesser Width along an axis normal to said stratum, each of said targets being adjustable toward and away from said oil stratum along its respective axis to vary the area of intersection with said oil stratum, and means for collecting oil that impinges upon each of said targets respectively.

2. In a self-contained unitary structure applicable to diversified machinery for delivering predetermined quantities or" oil to the respective bearings thereof, an enclosed reservoir for containing oil, a rotatable disk disposed within said reservoir above the surface of the oil therein, the axis of said disk being substantially vertical, means for rotating said disk, means for pumping said oil to the siu'face of said disk whereby oil may be scattered therefrom centrifugally in a substantially horizontal stratum, a generally horizontal wall defining a portion of said enclosed reservoir, said wall being positioned at an elevation below that of said rotatable disk, a plurality of tubular elements extending through said horizontal wall and having their top ends respectively positioned at an elevation below that of said rotatable disk, a target positioned axially above each tubular element and having a down-- wardly directed tip for dripping oil thereinto, each of said targets being disposed to intersect the oil stratum produced by said disk, a Ver tically extending wall forming part of said reservoir and extending upwardly from said horizontal wall, said vertical wall being spaced outwardly from said tubular elements so that oil in said oil stratum which passes said targets will engage said vertical wall and drain downwardly therefrom into said reservoir below the top ends of said tubular elements, and means leading from each tubular element for conducting oil therefrom to a bearing to be lubricated.

3. In a self-contained unitary structure applicable to diversified machinery for delivering predetermined quantities of oil to the respective bearings thereof, an enclosed reservoir for containing oil, a horizontally disposed rotatable disk within said reservoir above the level of the oil therein, an oil pump for pumping oil to the surface of said disk so that said oil may be scattered from said disk centrifugally in a substantially horizontal stratum, means within said reservoir to rotate said disk and actuate said oil pump, aplurality of downwardly tapered oil collectors each disposed to intersect said horizontal oil stratum on an axis normal thereto, each of said oil collectors being adjustable along its axis to vary the area of intersection with said oil stratum, an oil receiving means disposed below each of said collectors on the axis thereof for receiving oil which impinges upon and drips from the respective collector, each of said oil receivin means having an oil conducting tube leading therefrom to a respective one of said bearings.

4. In an oiling device of the class described, an enclosed reservoir for containing oil, a rotat able disk disposed in a horizontal plane within said reservoir above the level of the oil therein, an oil pump for supplying oil onto the upper surface of said disk, means for actuating said oil pump and rapidly rotating said disk whereby the oil thereon may be thrown centr'ifugally from said disk in the form of minute dropletstraveling in paths confined to a relatively thin horizontal stratum, a plurality of individual angularly spaced downwardly pointed cone-like targets movable into and through said stratum in a direction normal thereto, an adjusting means for each of said targets for adjusting the position thereof relative to the plane of said stratum, each of said adjusting means extending through the top wall of said reservoir, and means for collecting oil which impinges on and drips from each of said targets individually and leading to a respective bearing.
